Analytical model-based analysis of long-exposure images fromground-based telescopes
Lucie Leboulleux, Raphaël Galicher, Eric Gendron +2
The search for Earth-like exoplanets requires high-contrast and high-angular resolution instruments, which designs can be very complex: they need an adaptive optics system to compe…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
High contrast at small separation -- II. Impact on the dark hole of a realistic optical set-up with two deformable mirrors
M. Beaulieu, P. Martinez, L. Abe +3
Future large space- or ground-based telescopes will offer the resolution and sensitivity to probe the habitable zone of a large sample of nearby stars for exo-Earth imaging. To thi…
The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B
C. Lazzoni, A. Zurlo, S. Desidera +45
In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. In this paper, we focus our attention on substellar c…
The SPHERE infrared survey for exoplanets (SHINE). III. The demographics of young giant exoplanets below 300 au with SPHERE
A. Vigan, C. Fontanive, M. Meyer +108
The SHINE project is a 500-star survey performed with SPHERE on the VLT for the purpose of directly detecting new substellar companions and understanding their formation and early…
VLT/SPHERE survey for exoplanets around young, early-type stars including systems with multi-belt architectures
M. Lombart, G. Chauvin, P. Rojo +21
Dusty debris disks around pre- and main-sequence stars are potential signposts for the existence of planetesimals and exoplanets. Giant planet formation is therefore expected to pl…
